It all started when Dahl, a free-agent signee who played for the Rams from 2009 to 2012, said the Rams were able to beat and tie the 49ers in their two games last season partly because the 49ers were tipping their plays. That led to a response from the Rams cornerback, who called Dahl "lame and weak."

Cue Long, via Twitter:

i see where some niners fans talked pretty bad 2 @cortfinnegan today. just remember yall havent beaten us in 500 days or so

In truth, by the time the teams square off in Week 4, it will have been 634 days since the Rams lost to the 49ers. That calculates to one year, eight months, 25 days (or for you alternative time counters: 90 weeks; 15,216 hours; 912,960 minutes; 54,777,600 seconds).

We should, however, pump the breaks a bit on Long's celebration. Prior to the non-loss season series in 2012, the 49ersswept the Rams in 2011.

The most interesting stat: The Rams-49ers all-time series (including playoffs) shockingly sits dead even at 62-62-3.

The rubberest of rubber matches will be played Thursday, Sept. 26, on NFL Network (call your local cable or satellite provider for channel info).
